Bob,
Just like your windo washer switch, Intermitent switch.
Less chance of staying on. Also a light to let you know it is on.

I have to disagree with Jim on this. Has to be a switch you can turn on and leave on, so you can deal with hose, or you better have super long arms.

They pull some amps, so a good quality swich is needed.

Agreed,
Use a 30-40A SPST toggle switch. It may take 5 minutes to empty, you don't want to stand there and hold the button that long.
There's a hose in the sewer, you can't easily forget it's on, plus its loud.

Because I have several, I used a snow plow lift switch. SPDT, ON-OFF-(ON)
This allows me to switch on or have momentary contact. I run full on until
the pump starts to suck air. Stop to let more collect and pulse until I'm
done.

Let me suggest that you use a 30 or 40 amp cube relay and a 30 CB. This thing draws a lot of current and the relay allows you to keep the electrical path to the motor as short as possible using heavy wire. I got power for the macerator from the rear mounted house batteries. So I mounted the relay and CB right there and ran a heavy wire direct to the macerator. For the coil side to the switch I ran a thin wire (probably 16 ir 18 gauge) to a convenient place inside the generator housing and used a lighted Autozone / Radipo Shack rocker switch. I also mounted an indicator light on the dash and ran a second wire up to the dash. After that I changed the indicator light to a second autozone lighted switch. So now if I am parked with the macerator hose already in the dump I can turn it on from inside and listen to it run. When the motor changes pitch, I know the tank is near empty and can turn it off. All without leaving the coach. The switch inside inside was an after thought. Originally it was only suppose to be a light.

Mine has a switch (40A) in the genset bay, mounmted so you can switch it through the louvers. Convenient.
